Agent United States Patent 3,446,345 SASH PROTECTORS Ottar Arvid Frosoy,47 Chestnut Hill Parkway, Islington, Ontario, Canada Filed Mar. 22,1968, Ser. No. 715,236 Int. Cl. B65d 85/30, 81/02; A47b 95/00 US. Cl.206-60 10 Claims ABSTRACT OF THE DISCLOSURE A plastic clip forattachment to the corners of door and wmdow sashes for spacing stackedsashes from each other and for protecting the corners of said sashes.

This invention relates to protector clips and is particularly directedto clips for protecting the corners of door and window sashes and forspacing door and window sashes from each other when stacked.

Door and window sashes frequently are damaged when stacked for storage,or while in transit, due to the sashes rubbing against each other andbeing struck at their exposed corners. Protectors designed to protectsashes here to have been complex in shape and costly to produce, ordifficult to attach to sashes, and therefore generally not satisfactory.

I have discovered a sash protector that substantially obviates theforegoing disadvantages which comprises a rigid plastic structureincluding a pair of opposed side walls each having a corner and a pairof end walls interconnecting said corners rigidly securing said sidewalls a predetermined spaced distance apart, a plurality of spaced,upstanding ribs formed on the inner surface of one of said side wallsdefining a space between the free edges of said ribs and the innersurface of other side wall for receiving a sash therein, and a detentdepending from one of said side walls for removable engagement of theprotector with said sash.

It is a principal object of the present invention, therefore, to providea protector clip for window and door sashes which will space the sashesfrom each other when stacked and which will envelop their corners in aprotective shield.

It is another object of the invention to provide a protector clip forattachment to the corners of a sash which is simple in construction andwhich can be quickly and readily removably attached to the sash.

And another object of the invention is the provision of a protector clipfor sashes which can be manufactured by conventional injection mouldingtechniques from an inexpensive thermoplastic.

These and other objects of the invention, and the manner in which theycan be attained, will become evident from the following description ofthe drawings, in which:

FIGURE 1 is a perspective view of an embodiment of the invention showingthe interior of the protector clip;

FIGURE 2 is a perspective view of the protector shown in FIGURE 1,rotated through 180, showing a sash in ghost lines with the protectorattached thereto;

FIGURE 3 is an elevation showing a plurality of sashes stacked one abovethe other, each sash having a protector of the invention;

FIGURE 4 is a perspective view of the bight of another embodiment ofprotector; and

FIGURE 5 is a perspective view of still another embodiment of theprotector showing a sash in ghost lines.

Like reference characters refer to like parts throughout the descriptionof the drawings.

With particular reference to FIGURES 1, 2 and 3, the embodiment of thesash protector shown therein comprises a pair of opposed side walls 12,14 joined a pre- 3,446,345 Patented May 27, 1969 determined distanceapart at their corners by end walls 16, 18 which are disposed atsubstantially right angles to each other. A plurality of upstanding ribs22 are formed on the inner surface of side wall 14 a spaced distanceapart from each other such that the space defined between the edges 24of the ribs 22 and the inner surface of side wall 12 are substantiallyequivalent to the thickness of a window or door sash, as designated bynumeral 26 in FIGURES 2. and 3. A detent comprising a projection 28formed in the bight of side wall 12 projects inwardly a distancesubstantially equal to the width of the sash to be received in theprotector such that bevelled stop 30 will positively engage the inneredge of sash 26, as indicated most clearly by ghost lines in FIGURE 2.

Protector 10 is formed of a rigid and tough plastic having high impactstrength such as polystyrene, polypropylene or polyethylene to providesufiicient rigidity to support a plurality of stacked window sashes 26while providing sutficient resiliency to permit the facile removal ofthe protector from a sash by lateral displacement of projection 28 tofree stop 30.

FIGURE 4 illustrates another embodiment of the intion wherein spacedside Walls 40, 42 are secured a predetermined distance apart by endwalls 44, 46. A plurality of spaced ribs 48 are formed on the inner sidewall of side wall 40 and a plurality of corresponding upstanding ribs 50are formed on the inner side of side wall 42 for receiving a sashtherebetween. A web 52 joining innermost ribs 50a, 50b is adapted toabut the face of the sash to be received in the protector and a stop 58is formed on web 52 for engagement with the sash received within theprotector.

An opening 60 is formed in one end wall to permit the projection of asash extension therethrough. It will be understood that opening 60 canbe formed in the end walls of any of the embodiments of the inventiondescribed therein for conformity with the shape of a sash.

FIGURE 5 shows a protector 70 having spaced side walls 72, 74 secured aspaced distance apart by end walls 76, 78. Upstanding ribs 80, 82 and 84formed in the inner face of side wall 74 are of different heights toCompensate for changes in thickness of the sash 86, shown by ghostlines. A projection 88 formed in the plane of side wall 72 has a stop 90for engaging the inner edge 92 of sash 86.

The protector of the present invention provides a number of importantadvantages. Corners of window and 'door sashes, most vulnerable todamage, are protected and the side surface of sashes are furtherprotected by spacing of sashes from each other when stacked in piles.The protector can be inexpensively manufactured by conventional plasticforming techniques such as injection moulding.

What I claim as new and desire to protect by Letters Patent of theUnited States is:

1. A sash protector comprising a pair of opposed side walls each havinga corner and a pair of end walls interconnecting said corners rigidlysecuring said side walls a predetermined spaced distance apart, aplurality of spaced, upstanding ribs formed on the inner surface of oneof said side walls defining a space between the free edges of said ribsand the inner surface of other side wall for receiving a sash therein,and a detent depending from one of said side walls for removableengagement of the protector with said sash.

2. In a sash protector as claimed in claim 1, said detent comprising aresilient projection depending from one of the side walls and a stopformed at the free end of the projection.

3. In a sash protector as claimed in claim 1, said upstanding ribs beingformed integral with and substantially normal to a wall of theprotector, and disposed substantially parallel to each other.

4. In a sash protector as claimed in claim 3, said parallel ribs beingdisposed at about 45 to the plane of the end walls.

5. In a sash protector as claimed in claim 3, said ribs being disposedsubstantially parallel to one end Wall.

6. In a sash protector as claimed in claim 4, said ribs being ofsubstantially equal height such that their free edges define a planesubstantially parallel to the plane of the opposed side wall.

7. In a sash protector as claimed in claim 2, one of said end Wallshaving an opening formed therein for permitting the projection of a sashextension therethrough.

8. In a sash protector as claimed in claim 1, a plurality of ribs formedon the inner surfaces of both the side walls.

9. In a sash protector as claimed in claim 8, a web joining the freeedges of a pair of ribs, and a detent formed on the web for engagementwith a sash.

10. In a sash protector as claimed in claim 1, said protector formed ofa rigid thermoplastic selected from the group consisting of polystyrene,polypropylene and polyethylene.
